Thailand is one of Southeast Asia’s fastest-growing digital economies. With a population that is increasingly mobile-first, digital payments are now part of everyday life. For international businesses selling to Thai customers, however, the biggest challenge remains checkout success.
Credit and debit cards remain important, but they often fall short. Many transactions are declined, card coverage is limited outside urban centers, and foreign exchange costs can discourage buyers. This results in abandoned checkouts and lost revenue opportunities.
PromptPay, Thailand’s national QR-based payment method overseen by the Bank of Thailand and National ITMX, has become the mainstream alternative. With more than 81 million registrations and billions of transactions every month, it is trusted by consumers across all sectors.
For global B2B and e-commerce businesses, enabling PromptPay alongside cards means fewer failed payments, higher authorization rates, and greater customer trust.
With Tazapay, you can offer PromptPay through a unified checkout that also supports cards and 80+ other local payment methods, going live within days.
Why PromptPay Matters for Cross-Border Businesses
PromptPay adoption has grown dramatically, making it an indispensable part of Thailand’s payment ecosystem:
- In March 2025, PromptPay had 81.06 million registrations, covering nearly the entire adult population.
- That same month, it processed 2.1 billion transactions worth more than 4.43 trillion baht, a 13% year-on-year increase.
- By July 2025, volumes reached 2.36 billion transactions in a single month, with a total value of about 4.5 trillion baht.
- Cross-border usage is accelerating. In February 2025, PromptPay cross-border QR transactions totaled 296 million baht, up 119% year over year.
- Adoption is also cultural. In 2024, 61.5% of Thailand’s population used QR codes monthly, placing the country among the world’s leaders in QR adoption.
This progression shows PromptPay’s journey from a domestic initiative to a critical tool for international businesses. Offering PromptPay at checkout has become an expectation, not a differentiator, for global merchants operating in Thailand.
Industry Use Cases Where PromptPay Boosts Checkout Success

E-commerce and Marketplaces
E-commerce platforms and online marketplaces often see high cart abandonment in Thailand due to card failures or customer hesitation.
By offering PromptPay alongside cards:
- Customers can pay instantly by scanning a QR code.
- Merchants capture more successful transactions.
- Conversions rise, and abandoned carts fall.
PromptPay has become a default option for Thai shoppers, so businesses that include it maximize completed orders and revenue.
Travel Businesses
Thailand’s travel industry is huge, and online booking platforms often face failed transactions at checkout. This is particularly challenging for mid-range purchases like hotel reservations or tour bookings.
PromptPay helps by:
- Allowing travelers to pay instantly in Thai Baht with a familiar method.
- Providing immediate confirmation, which increases booking confidence.
- Complementing cards, so businesses capture both cardholders and QR-preferred customers.
For online travel agencies and hotel platforms, PromptPay improves booking completion and reduces drop-offs.
Digital Products and Gaming
Thailand has one of Asia’s most engaged digital populations, with significant spending on gaming and online products. But micro-transactions and one-off purchases often fail on card-only checkouts.
PromptPay ensures:
- Small and mid-ticket digital purchases go through quickly.
- Younger demographics without international cards can still pay.
- Players and customers enjoy a seamless, familiar checkout.
This makes PromptPay especially valuable for digital platforms, app stores, and gaming companies serving Thai customers.
Education and EdTech Platforms
As online education grows in Thailand, payment access remains a barrier. Many students and professionals lack international-ready cards, making it difficult to enroll in global courses.
PromptPay solves this by:
- Providing a widely trusted payment option in Thai Baht.
- Reducing drop-offs caused by failed card transactions.
- Expanding reach for global edtech providers targeting Thai learners.
The Business Impact of Offering Both Cards and PromptPay
Businesses that provide multiple payment options serve more customers and reduce payment risk. In Thailand:
- Authorization rates improve, since PromptPay succeeds where cards fail.
- Cart abandonment decreases, as customers complete payments with their preferred method.
- Trust increases, thanks to the presence of a familiar local option.
- Cash flow is better, as PromptPay settlements are typically instant or same-day.
PromptPay complements cards rather than replacing them. Together, they capture the widest possible customer base and maximize checkout success.
Challenges Without Local Payment Methods Like PromptPay
Merchants relying only on cards or international transfers face:
- Lost revenue from customers unwilling or unable to use cards.
- High failure and decline rates.
- Checkout abandonment caused by friction.
- Delays and costs of cross-border transfers unsuitable for small and mid-value transactions.
Adding PromptPay addresses these risks and future-proofs your checkout strategy.
